[Definition]

ChEBI: (R)-mandelic acid is the (R)-enantiomer of mandelic acid. It has a role as a human xenobiotic metabolite. It is a conjugate acid of a (R)-mandelate. It is an enantiomer of a (S)-mandelic acid.
[Synthesis Reference(s)]

The Journal of Organic Chemistry, 33, p. 2565, 1968 DOI: 10.1021/jo01270a105
Synthetic Communications, 18, p. 2141, 1988 DOI: 10.1080/00397918808068285
[General Description]

(R)-(-)-Mandelic acid, a chiral resolving agent, is also used as a building block to synthesize pharmaceutical drugs such as penicillin and cephalosporin. It can be synthesized from (R,S)-mandelonitrile with high yield and enantioselectivity using nitrilase enzyme.
[Flammability and Explosibility]

Nonflammable
[Purification Methods]

Purify the mandelic acids by recrystallisation from H2O, *C6H6 or CHCl3. [Roger J Chem Soc 2168 1932,Jamison & Turner J Chem Soc 611 1942.] They have solubilities in H2O of ca 11% at 25o. [Banks & Davies J Chem Soc 73 1938.] The S-benzylisothiuronium salts has m 180o (from H2O) and [] D 25 (+) and (-) 57o (c20, EtOH) [El Masri et al. Biochem J 68 199 1958]. [Beilstein 10 IV 564.]
